Upgrade notes

In addition to the numerous improvements in Rspamd 3.5, this release introduces some notable changes to the supported platforms. We are excited to announce the provision of arm64 packages, extending Rspamd’s compatibility to a wider range of devices. However, as part of our commitment to providing up-to-date and secure software, we have removed support for outdated and end-of-life (EOL) Debian distributions, specifically Ubuntu Bionic and Debian Buster. This decision ensures that our users are running Rspamd on well-maintained platforms with active security updates. For more context on this change and guidance on upgrading your distribution, please refer to the following document

It is essential to carefully review the upgrading implications to ensure a smooth transition to Rspamd 3.5. These changes allow us to focus on delivering the best possible email filtering solution while promoting the use of secure and up-to-date platforms.

Rspamd 3.4 has been released

2022-11-05 00:00:00 +0000

We have released Rspamd 3.4 today. This is a bugfix release with no incompatible changes. Several new features have also been added. Here are the most important changes in this version explained.

Main changes

Sharing hyperscan database among Rspamd processes

Hyperscan databases are now shared between all Rspamd processes reducing memory footprint, especially when multiple worker processes are running.

Critical fix in the compatibility with the integrations and headers alterations

There was a critical compatibility issue, caused by the change in the milter_headers reply block that prevents some Rspamd integrations to be functional. In this release that issue has been fixed, and the compatibility with the previous output format has been restored.

Fix additional fields in the Redis schema

Some fields were no longer accepted in Redis settingsissue. Now it works correctly.

Rspamd 3.3 has been released

2022-10-01 00:00:00 +0000

We have released Rspamd 3.3 today. There are incompatible changes in this release, so please get familiar with the upgrade guide.

Here are the most important changes in this version explained.

Main changes

Reworked and redesigned symbols cache

Symbols cache is responsible for rules exectuion and planning. In this release, there was a major rework of it’s logic and functionality. For example, it can now keep track of timeouts, plan fast events before slow and implement real passthrough for the rules that define such a behaviour. It is useful, when you want some rule to be executed as quick as possible to block or pass evident spam/ham without wasting network/cpu resources. The major drawback of such a rework is that passthrough rules are now really passthrough and can prevent other rules from being executed (that is expected from the design, but it could be not the case before).

Critical fix in the neural network module

There was a regression introduced in the version 3.2 that prevented old keys in Redis to be cleaned that caused infinite Redis database growth. This is fixed in the release 3.3 and the mitigation of this bug are described in the upgrade guide.

DKIM parser now ignores unknown tags

By standard, DKIM checker must ignore unknown tags for forward compatibility. Rspamd will now behave properly and ignore unknown tags as specified in RFC.

Upstreams support in lua_http and lua_tcp modules

It is possible now to use the functionality of the upstreams directly in Lua modules that use lua_http and lua_tcp libraries. It allows better support of the names resolution, IPv6 support for resolving the hostnames and internal handling of the upstreams logic by C code automatically.

CNAME records support in the DNS resolver

Rspamd DNS resolver now supports querying and parsing of the CNAME records. This technique might be useful for fighting some specific spam patterns.

Various memory leaks detected and plugged

In this release, we have found and fixed a good bunch of memory leaks and memory corruptions in the code.

Rspamd 3.2 has been released

2022-03-26 00:00:00 +0000

We have released Rspamd 3.2 today. This version is mostly bugfix release with several new features implemented.

Here are the most important changes in this version explained.

Main changes

DNS over TCP support

For a long time, Rspamd was unable to switch to TCP when processing DNS replies that are too large to be transferred over UDP. The portion of such a messages was never high, but there are some notable examples of the records that cannot fit into a UDP packet even with EDNS0 extension enabled. That are mostly poorly maintained TXT records that contains lot’s of legacy Google verification junk. However, it affected the SPF authentication, so I have decided to implement TCP fallback after all.

BIMI support

Rspamd can now download and verify logotypes from a validated certificates using a dedicated helper written in Rust. With this plugin, Rspamd can enrich your emails, appending a header with the logotype image (in SVG format) if all BIMI validation steps were successful.

Average scan time

It is now possible to fetch an average messages scan time via Rspamd HTTP API, Prometheus endpoint and even via ps command (supported on some OS only).

Monitor helper tool

You can now attach a CLI helper to Rspamd to get some real time performance graphs directly from your terminal:


Cloudmark support

You can now use Cloudmark via the external services module.

Rspamd 3.0 has been released

2021-08-19 00:00:00 +0000

We have released Rspamd 3.0 today. The decision to increase the major version number was taken because of the significant changes in the internal architecture Rspamd in many parts, specifically (but not limited) related to the HTML parsing. Rspamd now includes a CSS parser that can deal with the modern emails and properly extract data from them. New code is now written not in Plain C but in C++17 (might be extended to C++20 in future). Hence, to build Rspamd from the source code one would need a C++17 compatible compiler. This release includes contributions from many people, but I would like to say special thanks to the following persons:

  • Anton Yuzhaninov for testing Rspamd and being patient when dealing with the bugs, as well as for the valuable feedback on almost all questions
  • Andrew Lewis for constant work on Lua plugins and suggestions about Rspamd architecture
  • Alexander Moisseev for WebUI support and rules testing

Here are the most important changes in this version explained.

Main changes

HTML parser rework

Rspamd now parses HTML using a DOM model, so it can build and construct a parsed tree of HTML tags instead of a simple ad-hoc parsing. Adding this feature was quite untrivial, as it required full rewrite of the HTML related code. However, we can see that the new parser can deal with emails in HTML format that were completely ruined by a previous parser. Furthermore, better representation of HTML could lead to more sophisticated rules that take HTML structure into account.

CSS parser

Rspamd now has an embedded CSS parser that is currently limited to simple selectors but it could be extended in future. In conjunction with the modern HTML parser, CSS support is very valuable to extract the content from emails and distinguish visible and invisible content precisely.

Amazon S3 support

Rspamd now includes AWS API support (e.g. their signatures schema) which allows to interact with Amazon cloud services directly from Lua API. A simple plugin that stores all messages in AWS S3 cloud has also been written.

DMARC reporting rework

Rspamd DMARC reporting has proven to be troublesome in the previous version. Therefore, I have decided to move reports sending logic to a dedicated tool called rspamadm dmarc_report. The usage of this tool and DMARC reports in principle is already documented.

DMARC munging support

From version 3.0, Rspamd supports DMARC munging for the mailing list. In this mode, Rspamd will change the From: header to some pre-defined address (e.g. a mailing list address) for those messages who have valid DMARC policy with reject/quarantine that would otherwise fail during mailing list forwarding. An example of this technique is defined here.

External relay plugin

Many plugins, such as SPF, are using IP address provided by an MTA to Rspamd directly. However, in many cases there is a trusted relay that do some initial processing and hides the actual sender’s IP address. With help of this new plugin, Rspamd can now ‘fix’ this issue by treating sender’s IP as it is reported by that trusted relay.

Bayes export tool

Rspamd now allows to save and restore bayes tokens using rspamadm bayes_dump subcommand. This feature allows to move tokens between instances of Rspamd, to merge them and to analyse them manually.

Pyzor support

Rspamd now supports Pyzor via external services plugin, thanks to @defkev for this work!

Monitoring rework

Monitoring tools are now awaken less frequently reducing load on the external modules.
